Enable AWS IAM Service Roles

Enablement of AWS IAM service roles is critical for securely delegating permissions to AWS services. This measure ensures that service roles are properly configured and used, allowing AWS services to interact with your resources securely, minimizing the risk of unauthorized actions, and ensuring compliance with security best practices and regulatory requirements.

This policy pack can help you configure the following for service roles:

  • Create IAM service role for configuration recording
  • Create IAM service role for default EC2 instance
  • Create IAM service role for flow logging
  • Create IAM service role for SSM notification
  • Create IAM service role for Guardrails global event handlers

Documentation

Getting Started

Requirements

Credentials

To create a policy pack through Terraform:

  • Ensure you have Turbot/Admin permissions (or higher) in Guardrails
  • Create access keys in Guardrails

And then set your credentials:

export TURBOT_WORKSPACE=myworkspace.acme.com
export TURBOT_ACCESS_KEY=acce6ac5-access-key-here
export TURBOT_SECRET_KEY=a8af61ec-secret-key-here

Please see Turbot Guardrails Provider authentication for additional authentication methods.

Usage

Install Policy Pack

Note

By default, installed policy packs are not attached to any resources.

Policy packs must be attached to resources in order for their policy settings to take effect.

Clone:

git clone https://github.com/turbot/guardrails-samples.git
cd guardrails-samples/policy_packs/aws/guardrails/policy_packs/aws/guardrails/enable_iam_service_roles

Run the Terraform to create the policy pack in your workspace:

terraform init
terraform plan

Then apply the changes:

terraform apply

Apply Policy Pack

Important

Attaching this policy pack in Guardrails will result in creation of resources in the target account. However, it is easy to remove those resources later, by setting the Stack's policy to Enforce: Not configured.

Log into your Guardrails workspace and attach the policy pack to a resource.

If this policy pack is attached to a Guardrails folder, its policies will be applied to all accounts and resources in that folder. The policy pack can also be attached to multiple resources.

For more information, please see Policy Packs.

Enable Enforcement

Tip

You can also update the policy settings in this policy pack directly in the Guardrails console.

Please note your Terraform state file will then become out of sync and the policy settings should then only be managed in the console.

By default, the policies are set to Check in the pack's policy settings. To enable automated enforcements, you can switch these policies settings by adding a comment to the Check setting and removing the comment from one of the listed enforcement options:

resource "turbot_policy_setting" "aws_turbot_service_roles_configured" {
  resource = turbot_policy_pack.main.id
  type     = "tmod:@turbot/aws#/policy/types/serviceRoles"
  # value    = "Check: Configured"
  value    = "Enforce: Configured"
}

Then re-apply the changes:

terraform plan
terraform apply
